Corrected entry: Ritchie and Eddie look out of their window at the riots and upon seeing blue lights (reflected on the wall, and on them) they say the Fire Brigade has arrived. In the UK, the Fire Brigade uses yellow and orange lights - the police use blue.
Correction: All emergency vehicles, Police, Fire and Ambulance, in the UK use blue lights. Orange/Yellow is used by non-emergency vehicles, such as tow-trucks and other larger vehicles as a warning and doctors sometimes use green lights.
Correction: The fire brigade use blue lights. A Google image search for "Fire Engine" easily proves this.
